I had about 3 possible companies come round but SLM stood out – they were really nice when they came round and they knew what they were talking about. Their customer service was absolutely excellent. The staff were brilliant, they worked and were clean/polite and they knew that they were in our house. They explained everything to do with our new boiler in detail and were most informative
They’ve got the right staff, right attitude, they go about work well and just carry on – they worked solidly. The electrician followed up and he was good, gave me advice – couldn’t fault them. I would recommend them to anyone as we couldn't have had anyone better.
